INDICATING DEVICE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed November 5, 1 9 14. 7 Serial No. 870,498.

To all to]: am it may concern:

die it known that we,Annoa E. GAUGTL and JERRY CAWBY, citizens of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Indicating Devices for Automobiles; and we do hereby declare thefollowing to be a full, clear, and exact description .of the invention, such as, will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates generally to indicators. and in particular to indicators for automobiles to indicate the direction of the machine.

One of the objects of this invention is to provide a device easy of manipulation and certain inaction.

Another object of this invention is to provide an arrangement simple in structure, compact in form and durable in action.

Other cbiects and advantages of this invention will be hereinafter set forth in the specificationgand claimed.

Similar characters of reference refer to similar parts throughout the specification and drawings, in which,

Figure 1 is an elevational view partly in r section of this device in assembled formation, and Fig. 2 is a transverse vertical sectional view of the indicating box.

In the drawings, 1 is the casing composed of the cylindrical shell 2. the backing 3, a glass cover 4. and a retaining reinforcement 5, placed within the shell 2 the rear edge of which reinforcement abuts the bracket 3, and the front end of which just fails to reach the inturned flanged edge 6, thereby leaving a groove 7 to properly seat the cover 4. A central bore 8 is formed through the backing 3 in which is seated a bushing member 9. that is retained in its seat by means of a threaded nut 10 sc ewed upon the inner end of the bushing. Through this bushing is horizontally mounted a shaft 11 adapted to be rotated therein, said shaft being properly retained in the bushing member by means of annular collars 12 and 13, said collar 13 being locked to its seat by means of the transverse cotter pin 14. An arrow 15 having a suitable bushing 16, is mounted upon the end of the shaft 11 adapted to be rotated thereby, said arrow having a counterweight 17 at one end and an indicating point 18 at the opposite end. A suitable metallic supporting bracket 19 is mounted by means of the fastening 20 to the backing 3', said bracket being formed integrally with the oppositely disposed solenoids 21 and 22, of any preferred form of structure or wrapping. This bracket 19 has a fastening flange 23, an offset portion 24 and a vertical support portion 25 which ends in a yoke portion 26, as clearly shown in Fig. 2 of the drawings. A core 27 common to both solenoids is formed to reciprocate back and forth, the central portion of which is composed of a rack 28. A pinion 29 is rigidly mounted upon the shafting 11, and is adapt ed to be engaged by the rack 28. Suitable oppositely disposed apertures 30 and 31 are formed through the backing 3 adjacent each outer end of the solenoids 21 and 22, and an aperture 32 is formed through the backing 3 adjacent the lower end 23 of the bracket 19.

Suitably mounted to the dash board or to the operating mechanism of an automobile is a backing 33 having fastened thereto by means of a suitable fastening device 341 a casing 35 through which. is formed a centrally disposed slot 36. A positive feed wire 37 runs from the solenoid 22 through the aperture 31 and thence through the backing 33 to a contact 38 upon the interior face of the backing 33. A second opposite feed wire 39 runs from the solenoid 21 through the aperture 30 to and through the backing 33, likewise ending in a contact 40. A main positive feed wire 4L1 runs from the battery 42 to near the backing 33 where said feed wire 40 is divided in the branch feed wire 42 and the branch feed wire 43. each end of said branch feed wires penetrating through the backing 33 and ending in contacts 44: and 45, each one of which is adjacent contacts 38 and 40, previously noted. A suitable switch 46. having an arm 48, is adapted to reciprocate across the interior surface of the backing 33 so that each opposite end thereof will alternately engage with the contacts 38 and 4:4: on one side, or 40 and 45 on the opposite side. A push button 49 is formed to the support 48 and operates through the slot 36 in the casing 35, previously noted. so that said switch can be manually operated to alternately engage each pair of contacts. Opposi'telv disposed coil springs 50 and 51 are mounted between the casing 35 and the support 48 to normally hold said switch centrally disposed. A signal bulb 52 is mounted within the casing at one side and suitably connected to the feed wire 39, and a second bulb 53 is mounted in the opposite side of the casing and connected to the feed wire 37. A negative return wire 54: is connected to the lower end 20 of the bracket 19, passes through the aperture 32 out of the casing and returns to the battery 42? in the usual manner, and suitable return wires 54 and 54 are connected between each of the bulbs 52 and 53 and the return wire 54/ through the wire 41, wire 453, contact L5,

switch 4", contact 40, and the wire 39 to the solenoid 21 and from the solenoid 21 through the support 19. and rcturnwire 54c, thence back to the battery. This act energizes the solenoid 21 to draw to the right the core 27, which through the medium of the rack 28 fiCtUfltQS the pinion 29. This operates the shaft wh ch in turn rotates the indicator 15- to a position shown in dotted lines in Fig. 1, indicating that the auto mobile or vehicle is intending to turn in that Copies 0? this .patent may be 'obtained for direction. This at the same time energizes the circuit through the bulb 52 for the purpose of signaling at night time when the porting bracket having a yoke semi-cylin-, drical 1n crosssect on connecting said so1e-' nojds, a core .reciproca'tingly mounted in said solenoids having a rackto'engage the gear, said rack traveling in said yoke, a battery in circuit with the solenoids, contacts in the battery circuit, shuntcircuits including lamp in circuit with the main circuit, and a sliding switch for controlling the main and shunt circuits.

In testimony' whereof we have signed our names to this specification in the presence of two subscribing witnesses, ARDOR E. GAUGH.
